Embodiment 1

[0031] (1) Supercritical extraction treatment: The traditional shredded tobacco with a moisture content of 12% is subjected to supercritical extraction. The extraction temperature is 50°C and the extraction pressure is 35MPa. The inlet and outlet of the extraction kettle are closed, and the extraction is left to stand for 3 hours. Press to make all the extracts cover the surface of the shredded tobacco, take it out and set aside;

[0032] (2) Take the shredded tobacco after static extraction and place it in an oven, dry it at 100°C for 1 hour, with a moisture content of 1%, and set it aside;

[0033] (3) Take 30 g of shredded tobacco after oven treatment, then add 4.5 g of propylene glycol and glycerin mixture, and immediately place it in an environment with a temperature of 20° C. and a relative humidity of 60% for 48 hours to obtain a traditional shredded tobacco raw material suitable for heating without burning ;

Abstract

The invention provides a method for static extraction treatment of shredded tobacco suitable for heating without burning. The steps are as follows: 1). Take the tobacco raw material for use; 2). Place the tobacco raw material in step 1) in a supercritical extraction device. Under a certain extraction pressure and temperature, after the extraction time is reached, the pressure is released so that all the extracts are covered on the surface of the shredded tobacco; the extraction temperature is 40-50°C, and the time is 2-5h; the extraction pressure is 25-35MPa, The separation pressure is 4-8MPa; 3). Place the shredded tobacco treated in step 2) in an oven, dry it, and take it out for later use; 4). Mix the shredded tobacco obtained in step 3) with a humectant evenly Afterwards, balance processing for a period of time.

Description

technical field [0001] The invention relates to the field of novel tobacco products, in particular to a static extraction treatment method suitable for shredded tobacco in a heat-not-burn state. Background technique [0002] The research and development of new tobacco products is one of the latest major projects determined by the National Bureau. At present, representative heat-not-burn products in the international market are divided into electric heating and carbon heating products, which are characterized by not directly burning cigarettes but through Heating the tobacco material releases smoke, which reduces the harmful components produced by the pyrolysis of tobacco due to high-temperature combustion, and reduces the harmful components of mainstream smoke. Among them, the research on the matrix in the heating section, one of the key technologies of new tobacco products, is particularly important. It mainly focuses on solving the problem that the tobacco extract can be r...
